How big is the average alfalfa & hay operation in Iowa?

USDA's 2022 Census of Agriculture reports about 35 harvested acres of alfalfa & hay per operation in Iowa, averaged across 18,750 farms (656,618 acres total).

Is average operation size the same as field size?

No — and it's the most common mix-up. The 35-acre figure is the average alfalfa & hay acreage per farm; most farms split that across several fields, so a single field is typically smaller. For a real field boundary, trace it on satellite with the field mapper.

How much does it cost to spray a 35-acre alfalfa & hay field by drone in Iowa?

Roughly $274–$617 for a single application (about $8–$18/acre, application only — product is extra). Extra passes, higher carrier volume, or restricted-use products raise it. Use the calculator above to adjust.

How do I measure my exact alfalfa & hay field?
